Y'all
I have for the most part been able to successfully to put filters in
place but still enable NFS connections to our NetApp filer to remain.
That is, it appears that the ports that NetApp has assigned for the
various services are static (as I believe the appliance is based on
NetBSD which I understand uses static ports).
For example, on two different NetApp filers I'm seeing the same port
assignments

On occasion I'm seeing packets like below popping up in the logs; seems
like "late" packets past the window of the state table possibly as they
are labeled as OOW (out of window).
Am I understanding the nature of this OOW packet? Seeing it on SSH,
SMTP connections too I believe.
Is there anything I can do to address these? Would one of the tweaks
for /etc/system such as ipf.fr_tcpidletimeout or ipf.fr_tcpclosed be
able to fix this and if so what value / which way (up/down?)???
